SPECIFICATION forming part of Letters Patent No. 767,570, dated August 16, 1904. Application filed February 3, 1903. Serial No. 141,741. \No model.)

' To all whom it may concern:

Be it known that I, CARL KURTH, paymaster, a subject of the King of Prussia, German Emperor, residing at 40 N eustabterstrasse, Magdeburg, Germany, have invented a new and useful Improvement in Cartridges for 3 f, the choke.

Firearms, of which the following is a specification. p

This invention concerns a cartridge for guns and firearms of all kinds. Its object is to obtain an increased eifect of the cartridge and to reduce the recoil, while the quantity of powder used remains the same as in the present cartridges in use. This effect is obtained by the arrangement hereinafter described and as shown, for example, in the drawings of a cartridge for a fowling-piece.

The cartridge of this invention has in close connection to the powder a free space full of air in such amanner that the explosive matter is safely stored and prevented from moving, which would render it useless and cause danger by explosion.

Figure 1 is a longitudinal section of the cartridge; Fig. 2, the ring to be set in.

The letter a shows the bottom part of cartridge; b, the gunpowder; c, the wad, which in the cartridge now used presses tight on the gunpowder; (Z, the-shot; e, the covering-disk;

All these parts remain unchanged in the present cartridge.

9 is a small cardboard cylinder or case closed at one opening with an easily-combustible gauze-like net it.

The cartridge case of my invention is slightly longer than the ordinary cartridgecase on account of the cardboard air-chamber, the other parts of both cartridges being the The order of the parts when constructing a cartridge according to this invention is as follows: bottom part a, powder 7), cardboard cylinder or case 9 with net It, wad 0, shot 0?, disk e, and choke f.

There is between the plug 0 and the powder 6 a quantity of air, which has the effect of increasing the combustion of the powder.

It is easily proved by an experiment with one of the cartridges in use that a considerable large quantity of unburned powder flies out of the barrel with the wad, the explosive power of which is thus lost. This is entirely avoided by the present invention. By inclosing a quantity of air with the powder a complete and rapid combustion of the whole pow.-

der is accomplished, and thus a greater effect .of force is obtained.

This invention can be used with the same advantage for ball or bullet cartridges. In this case the wad is not necessary.

What I claim as my invention, and-desire to secure by Letters Patent, is,

In a-cartridge for firearms the combination of the explosive propelling charge, an easilycombustible diaphragm lying on the charge, a ring-like cardboard cylinder and a wad pressing said cylinder on the diaphragm close to the powder, all as described and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

CARL KURTH.
